Hi all,
the first patch fixes the ohci-sm501 regression that Guenther reported
due to the platform device dma_mask changes. The second one ports that
fix to another driver that works the same way. The rest cleans up
various loose ends left over from the dma related usb changes in the
last two merge windows.

Now that these drivers use the usb localmem pool there is no need to
select DMA_DECLARE_COHERENT.
